Tracks Trigger size for ambient track sounds

[mboyd5]

Hi, I've recently figured out how to add ambient track sounds using CSP thanks to the tutorials posted on here but my problem is how do you make the trigger size larger? It seems to be limited to around 10.4 metres in game and for whatever reason it won't bind to the object using the "RELATIVE_TO =" line in the ext_config file.

I've attached a youtube video for reference. Ignore the giant pink balls as I was trying to use them to figure out how big the trigger zone was.
